DETAILED DESCRIPTION OF THE EMBODIMENTS

It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein.

The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure.

Several definitions that apply throughout this disclosure will now be presented.

As shown in FIG.1 through FIG. 6, in one embodiment, an electronic cigarette includes an oil container 10, an atomizing unit 20, a circuit unit 30, and a sealing plug 40. The oil container 10 includes a smoke passage 11, a container base 15, and an atomizing chamber 12 located on an upper portion of the container base 15. The oil container 10 defines an oil inlet 14 in a top portion of the container base 10, and defines an oil outlet 13 in the container base 10 towards the atomizing chamber 12. A container latch 16 is located on a lower portion of the oil container 10. The circuit unit 30 defines a slot corresponding to the container latch 16. The oil container 10 can be secured to or detached from the circuit unit 30 through couple of the container latch 16 and the slot.

A retaining protuberance 24 is located on a middle portion of the atomizing unit 20. An upper sealing ring 23 and a lower sealing ring 25 are attached to the retaining protuberance 24 at two opposite sides. The upper sealing ring 23 and the lower sealing ring 25 can seal the atomizing chamber 12. An oil deflecting hole 22 is defined in the upper portion of the atomizing unit 20. The lower portion of the atomizing unit 20 can be coupled to the circuit unit 30. When the oil container 10 is detached, the lower portion of the oil container 10 can be screwed to the sealing plug 40. A silicon rubber of the sealing plug 40 can extend into the atomizing chamber 12 to seal the oil container 10.

In one embodiment, the smoke passage 11 and the atomizing chamber 12 are sealed through the silicon rubber. The upper portion of the atomizing unit 20 can seal the atomizing chamber 12 through plugging, screwing or latching. The lower portion of the atomizing unit 20 can seal the circuit unit 30 through screwing or latching. The container latch 16 can be screwed to the sealing plug 40.

In one embodiment, the oil container and the circuit unit can be detached through the container latch. The atomizing unit and the oil container can be sealed and detached. Furthermore, the oil container and the atomizing unit can mounted to the circuit unit separately. Thus, the oil container, the atomizing unit and the circuit unit can be separately mounted.

When the atomizing unit is detached from the oil container, the oil is maintained in the oil container due to balance of the air pressure and surface tension of the oil, and the oil container is self-sealed without leak.

In the embodiment, the electronic cigarette may have the following advantages. First, due to the detachable configuration, the atomizing unit can be changed separately when it is damaged or worn-out, there is no need to change a whole traditional integrated atomizer, and use cost is lowered. It can promote environmental protection. Second, some oil containers are one-off use, and the oil cannot be infused during use, the oil in these oil containers may be use out before the service lift of the atomizing unit. The oil container can be detached and changed separately, instead of changing the whole atomizer, use cost is lowered. It can also promote environmental protection. Third, some oil containers can be used to receive the oil during use. Four, due to the detached oil container, user can chose different smell or taste of oil, and there is no need to change the whole atomizer to have different taste. The use cost is significant reduced. Five, the oil container can be easily and quickly detached from the circuit unit and can be sealed by the sealing plug. It can prevent oil leaking in a flight or in high altitude locality.
